Various improvements (#547)

- Fixed crash when returning to Setup app (from any of the steps)
- Fixed crash when returning to TimeDateSettings app (after locale selection)
- Fixed GuiService inconsistent behaviour: now always perform operations async (e.g. to show/hide apps). This fixes crashes in some onHide() calls where onHide() might be called before onShow() was called.
- Fix for incorrect WebServService path
- Remove CYD-4848S040C SD card functionality, but added a GPIO fix for releasing 3-wire SPI pin sharing.
- Fix for saving/loading settings for various apps
